<P>The rapid identification and verification of single nucleotide polymorphisms (SNPs) were demonstrated using a well array sensor containing anti-biofouling titanium (Ti). Probe single-stranded DNA (ssDNA) was immobilized inside a titanium-well array on amine-modified glass surfaces with anti-biofouling behavior via a streptavidin-biotin interaction. Fluorescence intensity changes originating from the hybridization of nucleic acids to protein-bound nucleic acids linked to Alexa Fluor (FL) 647 were observed. The protocol was highly sensitive and reproducible for the detection of DNA hybridization. Significant changes in fluorescence signals were observed when using target DNA with a single base mismatch, indicating that this method is applicable to SNP detection. The microarray technology for the detection of SNPs using anti-biofouling Ti and other methods can be used as a highly sensitive in vitro medical sensor, as highlighted by an increase in genotyping accuracy.</P>

Background: In patients with peptic ulcer bleeding (PUB), the prevalence rate of Helicobacter pylori infection may be underestimated. The causes for decreased diagnostic sensitivity of H. pylori test in PUB are still controversial. We aim to investigate the diagnostic yield of Polymerase Chain Reaction (PCR) to the detection of H. pylori in PUB. Methods: A consecutive series of patients who had PUB and admitted to the hospital between 2012 and 2013 were enrolled, and a total of 170 patients were analyzed. During the 2nd look endoscopy, two sets of gastric biopsy specimens were taken from the greater curvature of the mid-antrum and corpus for histology and CLO test. After interpretation of CLO test, the tissue samples from the kit were used, and dual-priming oligonucleotide-based multiplex PCR (DPO-PCR) was performed to the detection of H. pylori and antibiotic resistance. If the result was H. pylori -negative, re-biopsy specimens under endoscopy was taken after 4~8 weeks of initial examination. Results: In PUB, the prevalence rate of H. pylori infection was 63.4% (104/164). At initial diagnostic sensitivities of histology, CLO test, and PCR test were 70.2% (73/104), 51.9% (54/104) and 92.3% (96/104), respectively (P<0.01). The rate of clarithromycin resistance by using the 23S rRNA point mutation was 22.1% (23/104). Conclusions: For diagnosis of H. pylori infection in PUB, DPO-PCR test with tissue sample from CLO test kit were the most sensitive test. Additionally, the information of clarithromycin resistance would be helpful for selection of the eradication regimens for H. pylori.

The whole gal/lae operon genes of Lactococcus lactis ssp. lactis 7962 were reported as follows: galA-galM-galK-galT-lacA -lacZ-galE. The galK gene encoding a galactokinase involved in one of the Leloir pathways for galactose metabolism was found to be 1,197 bp in length and encodes a protein of 43,822 Da calculated molecular mass. The deduced amino acid sequence showed over 50% homology with GaIK proteins from several other lactic acid bacteria. The galK gene was expressed in E. coli and the product was identified as a 43 kDa protein which corresponds to the estimated size from the DNA sequence. The galactokinase activity of recombinant 5. coli was about 8 times greater against that of the host strain and more than 3 times higher than the induced L. lactis 7962.

Background/Aims: Pneumocystis jirovecii polymerase chain reaction (PCR) can be helpful in diagnosing Pneumocystis pneumonia (PCP); however it has limitations. We evaluated the prevalence of positive P. jirovecii PCR from non-human immunodeficiency virus (HIV) immunocompromised patients and tried to determine the risk of PCP development. Methods: Between May 2009 and September 2012, P. jirovecii PCR was performed in bronchoscopic specimens from 1,231 adult non-HIV immunocompromised patients suspected of respiratory infection. Only 169 patients (13.7%) who were tested positive for P. jirovecii PCR were enrolled. Retrospective chart review was performed. PCP was defined in patients with positive P. jirovecii PCR who were treated for PCP based on the clinical decision. Results: From 169 P. jirovecii PCR-positive patients, 90 patients were in the PCP group (53.3%) and 79 patients were in the non-PCP group (46.7%). In the PCP group, 38% of patients expired or aggravated after therapy, whereas the majority of patients (84%) in the non-PCP group recovered without treatment for PCP. Independent risk factors for PCP by binary logistic regression analysis were underlying conditions- hematological malignancies, solid tumors or solid organ transplantation, dyspnea, age < 60 years, and albumin < 2.9 g/dL. Conclusions: This study suggests that not all P. jirovecii PCR-positive patients need to be treated for PCP. Among P. jirovecii PCR-positive patients, those who are less than 60 years old, with hematological malignancies, solid tumors or solid organ transplantation, low albumin, and with symptoms of dyspnea, the possibility of PCP might be higher. Treatment should also be selected to these patients.

Background: Gallstone pancreatitis (GSP) is a common condition, accounting for 30-40% of all pancreatitis cases. The recommended therapy for reducing the risk of recurrent attack is cholecystectmoy, and endoscopic sphincterotomy (EST) is another therapeutic option after GSP. We aimed to access the long term results of GSP using cholecystectomy and endoscopic sphincterotomy. In addition, characteristics were evaluated when recurrent biliary symptoms happened. Methods: A consecutive series of patients who had GSP and more than 6 months follow up period were included. A total 171 episodes of AGP were enrolled in 148 patients. Results: Mean follow up period was 58 month (range 6-360 month). For prevention of recurrent biliary event, 30 (18%) had a cholecystectomy, 46 (27%) had an EST, and 25 (15%) had both procedures. 66 patients had no defi nitive treatment. Recurrent biliary events (pancreatitis, cholangitis, biliary pain) happened in 2 patients of cholecystectomy following by EST and 3 patients of cholecystectomy group. In non-surgical group, 14 patients of EST group, and 22 patients of no treatment group suffered from recurrent biliary symptoms (P<0.01). Recurrent pancreatitis was happened in 2 patients of EST group and 17 patients of conservative group (3% vs 26%, P=0.03). There was only one case of recurrent pancreatitis with previous cholecystectomy with EST, but, no signifi cant benefi t compared with cholecystectomy only group. Conclusions: Cholecystectomy provide additional protection for recurrent GSP as well as other biliary events. In non-surgical patients, EST offers more protective effect for the further bouts of pancreatitis.
Acceleration of poly(L-lactide) degradation by TiO2 nanoparticles in sunlight.
Lee, Jinyoung,Lee, Ju-Kyoung,Park, Bae Ho,Busnaina, Ahmed,Lee, Hea Yeon American Scientific Publishers 2013 Journal of Nanoscience and Nanotechnology Vol.13 No.10
<P>Poly(L-lactide) (PLA) is known to eventually be degraded into water and carbon dioxide by the microorganisms of the natural world. Titanium dioxide (TiO2) has been used in the biomedical and bioengineering fields as a photocatalyst. The purpose of this research project is to evaluate the influence of TiO2 added to PLA films both before and after irradiation of the films with sunlight. The PLA-TiO2 films were prepared by the addition of TiO2 (size: > 100 nm) nanoparticles to PLA. The surface changes of the PLA film were investigated before and after the films were exposed to sunlight. Tiny holes were observed in the PLA film without TiO2 nanoparticles after irradiation with sunlight, whereas large pits formed in the PLA-TiO2 films. It is suggested that PLA was degraded by the ultraviolet rays in sunlight. In addition, the decomposition speed was thought to be enhanced by the addition of TiO2, which acted as a catalyst.</P>

Hea Young Lee,Yeon Jae Bae 한국응용곤충학회 2011 한국응용곤충학회 학술대회논문집 Vol.2011 No.05
Korean species of the dragonfly family Gomphidae are reviewed based on a comprehensive specimen examination. The family can be easily recognized by separated compound eyes, yellowish body color, and similar features of triangle cells on fore- and hindwings. Since a report of 4 Korean species (Seiboldius japonicus, Gomphus melampus, G. postocularis, Gomphus sp.) of the family by Doi (1932), 18 species belonging to 13 genera were recorded by Lee (2006). In this study, we added 5 species and reviewed 23 species of Korean Gomphidae. Identification key and taxonomic remarks were provide: Asiagomphus pryeri is recorded for the first time in South Korea; 3 North Korean species in the genus Davidius are added; Gomphus postocularis is treated as subspecies Shaogomphus postocularis epophthalmus; larval stage of Burmagomphus KUa is identified as Burmagomphus collaris; Ophiogomphus forficula is the synonym of O. obscurus not O. reductus.
